How does a coking plant work? How does this work? The coal is heated to C in the coke ovens. .. During the distillation process, a large amount of gas and smoke is generated, which after purification creates coke oven gas and other valuable byproducts, such as tar, sulphur, ammonia, naphthalene and benzole.

Amongst other leaders that worked on this subject, Heinrich Koppers introduced the coke oven process into the US industry in 1907. Establishing Heinric Koppers AG in 1904, he created the socalled 'half direct' process for recovery tar and ammonia from coke oven gas. By 1923, 90 % of all coke oven plants in the Ruhr district used this process.

Coke is essentially the remaining carbon and ash. With byproduct ovens, the volatiles and combustion products are collected downstream of the oven chamber and refined in a chemical plant to produce coke oven gas and other products such as tar, ammonia, and benzol. In heat recovery ovens, all the coal volatiles are oxidized within the ovens.
